species of fish From Wikipedia, the free encyclopedia
Premnas biaculeatus, commonly known as spine-cheeked anemonefish or the maroon clownfish, is a species of anemonefish (found swimming near anemones) found in the Indo-Pacific from western Indonesia to Taiwan and the Great Barrier Reef.[2] They can grow up to be about 17 cm (6.7 in). Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. The female is largest, the breeding male is second largest, and the male nonbreeders get progressively smaller as the hierarchy descends.They exhibit protandry, meaning the breeding male changes to female if the sole breeding female dies, with the largest nonbreeder becoming the breeding male. The fish's natural diet includes algae and zooplankton.
